[Fis] Neuroinformation?

[Krassimir Markov]

Dear Bob,
I think, there is no conflict between two points of view – information may be a process and it may be a static depending of what kind of reflection it is.
For instance, we reflect the world around:
- as static - by photos, art images, sculptures, etc.; 
- as dynamic - by movies, theater plays, ballet, etc.; 
- and, at the end, by both types – by static text which creates dynamical imaginations in our consciousness.
Friendly regards
Krassimir

PS: This is my second post for this week. So, I say: Goodbye to the next one!

Dear all - I support Joseph's remarks and would suggest that information in general is a process that unfortunately is formulated as a noun. Inspired by Bucky Fuller's I think I am a verb I suggest that "Information is a verb" It is a verb because it describes a process. Although that solves one problem we need to be able to describe a set of signs that have the potential to initiate the process of informing through interpretation. I would not suggest we create another word but recognize that the word information has many meanings and that when it is describing a process it has a verb-like quality to it and when it describes a set of sign that have the potential to be interpreted and hence become information it is acting as a noun. I would also suggest that a simple definition of the term information is not possible because its meaning is so context dependent. This is true of all words but even more so for information. For those that agree with my sentiments the above is information and for those that do not it is nonsense. My best wishes to both groups,  Bob Logan

  Dear Dr. Isiegas,

  I will add my support to the extended concept of information that inheres in the work of Robert Ulanowicz and John Collier. I would just add that I like to call it information-as-process, to call attention to its 'structure' being dynamic, with individual neurones involved in a cyclic (better spiral or sinusoidal) movement between states of activation and inhibition. I have ascribed an extension of logic to this form of alternating actual and potential states in complex processes at all levels of reality.

  Best wishes,

  Joseph B.

  Dear Dr. Isiegas:

  I envision neuroinformation as the mutual information of the neuronal
  network where synaptic connections are weighted by the frequencies of
  discharge between all pairs of neurons. This is directly analogous to a
  network of trophic exchanges among an ecosystem, as illustrated in
  <http://people.biology.ufl.edu/ulan/pubs/SymmOvhd.PDF>.

  Please note that this measure is different from the conventional
  sender-channel-receiver format of communications theory. It resembles more
  the "structural information" inhering in the neuronal network. John
  Collier (also a FISer) calls such information "enformation" to draw
  attention to its different nature.

  With best wishes for success,

  Bob Ulanowicz


    Dear list,



       I have been reading during the last year all these interesting

    exchanges. Some of them terrific discussions! Given my scientific

    backgound

    (Molecular Neuroscience), I would like to hear your point of view on the

    topic of neuroinformation, how information "exists" within the Central

    Nervous Systems. My task was experimental; I was interested in

    investigating the molecular mechanisms underlying learning and memory,

    specifically, the role of the cAMP-PKA-CREB signaling pathway in such

    brain

    functions (In Ted Abel´s Lab at the University of Pennsylvania, where I

    spent 7 years). I generated several genetically modified mice in which I

    could regulate the expression of this pathway in specific brain regions

    and

    in which I studied the effects of upregulation or downregulation at the

    synaptic and behavioral levels. However, I am conscious that the

    "information flow" within the mouse Nervous System is far more complex

    that

    in the "simple" pathway that I was studying...so, my concrete question for

    you "Fishers" or "Fisers", how should we contemplate the micro and macro

    structures of information within the neural realm? what is

    Neuroinformation?



    Best wishes,
